So I need to be off the clock tonight by 9:40 to have the DoT required amount of time off between shifts. Problem is the sort doesn't start until 6:50. This raises a couple of questions: 1. Which shift takes precedence? Twilight sort is my primary job but Saturday Air is arguably more important to the company then a Friday sort they usually over staff anyway, especially if they can't get another driver to cover my route tomorrow. Does the contract require I be allowed to clock out in time to make the start time for tomorrow or can my twilight supervisor me and the Saturday supervisor over by keeping me on the clock? 2. Can I still get my 3.5 hour guarantee (I would obviously have to start early) or am I basically willingly forfeiting it by "requesting to leave early" to make tomorrow's start time?
